TECHNICAL FIELD

The present invention relates to the field of Internet technologies, and more particularly to touch-based creation of a media item.

BACKGROUND OF THE INVENTION

As wireless networks and the processing power of mobile devices have improved, web-based applications increasingly allow everyday users to create original content in real-time without professional software. For example, Instagram and Vine allow a user to create original media content that is personalized to the user's tastes—anytime and anywhere. Despite the advances in the provision of web-based media creation applications, some solutions for creating media content are clumsy or ill-suited to future improvements in provisioning media content.

SUMMARY

Various implementations of methods and devices within the scope of the appended claims each have several aspects, no single one of which is solely responsible for the attributes described herein. Without limiting the scope of the appended claims, after considering this disclosure, and particularly after considering the section entitled “Detailed Description” one will understand how the aspects of various implementations are used to generate a media item.

In some embodiments, a client-side method of generating a media item is performed at a client device (e.g., client device 104, FIGS. 1-2) with one or more processors and memory. The method includes displaying a first user interface including a plurality of audio tracks. The method also includes: detecting a first user input selecting one of the plurality of audio tracks; and in response to detecting the first user input, displaying a second user interface for recording a video clip. The method also includes: detecting a second user input to initiate recording of the video clip; and detecting a third user input to stop recording of the video clip. The method further includes: detecting a fourth user input to publish the media item based on the video clip and the selected audio track; and in response to detecting the fourth user input, publishing the media item to a server, including sending to the server information identifying the selected audio track, the video clip, and information related to synchronization of the selected audio track and the video clip.

In some embodiments, a server-side method of generating a media item is performed at a server system (e.g., server system 108, FIGS. 1 and 3) with one or more processors and memory. The method includes: receiving first information, from a client device, identifying at least a portion of an audio track associated with the media item; and receiving second information, from the client device, identifying one or more media files associated with the media item. The method also includes generating a metadata structure corresponding to the media item generated by the client device, where: the metadata structure enables synchronization of at least the portion of the audio track with the one or more media files; and the metadata structure includes: a pointer to the audio track identified by the first information; and a pointer to the one or more media files identified by the second information.

In some embodiments, an electronic device or a computer system (e.g., client device 104, FIGS. 1-2 or server system 108, FIGS. 1 and 3) includes one or more processors and memory storing one or more programs for execution by the one or more processors, the one or more programs include instructions for performing the operations of the methods described herein. In some embodiments, a non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by an electronic device or a computer system (e.g., client device 104, FIGS. 1-2 or server system 108, FIGS. 1 and 3) with one or more processors, cause the electronic device or computer system to perform the operations of the methods described herein.

DETAILED DESCRIPTION

Numerous details are described herein in order to provide a thorough understanding of the example implementations illustrated in the accompanying drawings. However, some embodiments may be practiced without many of the specific details, and the scope of the claims is only limited by those features and aspects specifically recited in the claims. Furthermore, well-known methods, components, and circuits have not been described in exhaustive detail so as not to unnecessarily obscure more pertinent aspects of the implementations described herein.

As shown in FIG. 1, an application for generating, exploring, and presenting media items is implemented in a server-client environment 100 in accordance with some embodiments. In some embodiments, the application includes client-side processing 102-1, 102-2 (hereinafter “client-side module 102”) executed on a client device 104-1, 104-2 and server-side processing 106 (hereinafter “server-side module 106”) executed on a server system 108. Client-side module 102 communicates with server-side module 106 through one or more networks 110. Client-side module 102 provides client-side functionalities associated with the application (e.g., creation and presentation of media items) such as client-facing input and output processing and communications with server-side module 106. Server-side module 106 provides server-side functionalities associated with the application (e.g., generating metadata structures for, storing portions of, and causing/directing presentation of media items) for any number of client modules 102 each residing on a respective client device 104.

In some embodiments, server-side module 106 includes one or more processors 112, media files database 114, media item metadata database 116, an I/O interface to one or more clients 118, and an I/O interface to one or more external services 120. I/O interface to one or more clients 118 facilitates the client-facing input and output processing for server-side module 106. One or more processors 112 receive requests from client-side module 102 to create media items or obtain media items for presentation. Media files database 114 stores media files, such as images and/or video clips, associated with media items, and media item metadata database 116 stores a metadata structure for each media item, where each metadata structure associates one or more media files and at least a portion of an audio track with a media item. In some embodiments, media files database 114 and media item metadata database 116 are communicatively coupled with but located remotely from server system 116. In some embodiments, media files database 114 and media item metadata database 116 are located separately from one another. In some embodiments, server-side module 106 communicates with one or more external services such as audio sources 124 a . . . 124 n (e.g., streaming audio service providers such as Spotify, SoundCloud, Rdio, Pandora, and the like) and media file sources 126 a . . . 126 n (e.g., service providers of images and/or video such as YouTube, Vimeo, Vine, Flickr, Imgur, and the like) through one or more networks 110. I/O interface to one or more external services 120 facilitates such communications.

Examples of client device 104 include, but are not limited to, a handheld computer, a wearable computing device (e.g., Google Glass or a smart watch), a biologically implanted computing device, a personal digital assistant (PDA), a tablet computer, a laptop computer, a desktop computer, a cellular telephone, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a media player, a navigation device, a game console, a television, a remote control, or a combination of any two or more of these data processing devices or other data processing devices.

Examples of one or more networks 110 include local area networks (“LAN”) and wide area networks (“WAN”) such as the Internet. One or more networks 110 are, optionally, implemented using any known network protocol, including various wired or wireless protocols, such as Ethernet, Universal Serial Bus (USB), FIREWIRE, Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wi-Fi, voice over Internet Protocol (VoIP), Wi-MAX, or any other suitable communication protocol.

In some embodiments, server system 108 is managed by the provider of the application for generating, exploring, and presenting media items. Server system 108 is implemented on one or more standalone data processing apparatuses or a distributed network of computers. In some embodiments, server system 108 also employs various virtual devices and/or services of third party service providers (e.g., third-party cloud service providers) to provide the underlying computing resources and/or infrastructure resources of server system 108.

Although server-client environment 100 shown in FIG. 1 includes both a client-side portion (e.g., client-side module 102) and a server-side portion (e.g., server-side module 106), in some embodiments, the application is implemented as a standalone application installed on client device 104. In addition, the division of functionalities between the client and server portions can vary in different embodiments. For example, in some embodiments, client-side module 102 is a thin-client that provides only user-facing input and output processing functions, and delegates all other data processing functionalities to a backend server (e.g., server system 108).

FIG. 2 is a block diagram illustrating a representative client device 104 associated with a user in accordance with some embodiments. Client device 104, typically, includes one or more processing units (CPUs) 202, one or more network interfaces 204, memory 206, and one or more communication buses 208 for interconnecting these components (sometimes called a chipset).

In some embodiments, memory 206 also includes a client-side module 102 associated with an application for creating, exploring, and playing back media items that includes, but is not limited to:

-   -   displaying module 224 for displaying user interfaces of the         application;     -   detecting module 226 for detecting one or more user inputs         corresponding to the application;     -   recording module 228 for recording live and/or pre-existing         video clips and/or images for a media item;     -   editing module 230 for reordering, deleting, and otherwise         editing video clips in a media item prior to publishing the         media item;     -   effects module 232 for applying video and/or audio effects to         the media item prior to publishing the media item;     -   preview module 234 for presenting at least a portion of the         media item prior to publishing the media item;     -   publishing module 236 for causing the media item to be published         by at least sending, to server system 108, first information         identifying at least a portion of an audio track associated with         the media item and second information identifying one or more         media files associated with the media item; and     -   sharing module 238 for sharing the media item via one or more         sharing methods (e.g., email, SMS, social media outlets, etc.).

In some embodiments, memory 206 also includes client data 250 for storing data for the application. Client data 250 includes, but is not limited to:

-   -   video library 252 storing one or more pre-existing video clips         recorded prior to executing the application;     -   image library 254 storing one or more pre-existing images         captured prior to executing the application;     -   audio library 256 storing one or more pre-existing audio tracks         created or stored prior to executing the application;     -   effects library 258 including functions for implementing one or         more real-time or post-processed audio and/or video effects         (e.g., OpenGL Shading Language (GLSL) shaders); and     -   user profile 260 including a plurality of preferences associated         with the application for the user of client device 104.

Each of the above identified elements may be stored in one or more of the previously mentioned memory devices, and corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures, modules or data structures, and thus various subsets of these modules may be combined or otherwise re-arranged in various implementations. In some implementations, memory 206, optionally, stores a subset of the modules and data structures identified above. Furthermore, memory 206, optionally, stores additional modules and data structures not described above.

Furthermore, memory 306, optionally, stores additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces and associated processes that may be implemented on a respective client device 104 with one or more speakers 402 enabled to output sound, zero or more microphones 404 enabled to receive sound input, and a touch screen 406 enabled to receive one or more contacts and display information (e.g., media content, webpages and/or user interfaces for an application). FIGS. 4A-4Z illustrate example user interfaces for generating a media item in accordance with some embodiments.

Although some of the examples that follow will be given with reference to inputs on touch screen 406 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display. In some embodiments, the touch sensitive surface has a primary axis that corresponds to a primary axis on the display. In accordance with these embodiments, the device detects contacts with the touch-sensitive surface at locations that correspond to respective locations on the display. In this way, user inputs detected by the device on the touch-sensitive surface are used by the device to manipulate the user interface on the display of the device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

FIGS. 4A-4Z show user interfaces 408 displayed on client device 104 (e.g., a mobile phone) for an application for generating, exploring, and presenting media items; however, one skilled in the art will appreciate that the user interfaces shown in FIGS. 4A-4Z may be implemented on other similar computing devices. The user interfaces in FIGS. 4A-4Z are used to illustrate the processes described herein, including the processes described with respect to FIGS. 6A-6F.

FIG. 4A illustrates client device 104 displaying a first user interface of a process for generating a media item on touch screen 406. In FIG. 4A, the first user interface prompts the user of client device 104 to choose an audio track for the media item. In FIG. 4A, the user interface includes search query box 414 for searching for audio tracks and a plurality of audio track affordances 416 corresponding to audio tracks. In some embodiments, audio track affordances 416 corresponding to sponsored audio tracks are displayed at the top or near the top of the feed of first user interface. In some embodiments, each audio track affordance 416 includes album cover art or an associated image, artist name, and track title for the corresponding audio track. In FIG. 4A, each audio track affordance 416 includes a source indicator 418. For example, source indicator 418-a displays an “L” indicating that the audio track corresponding to audio track affordance 416-a is available locally (i.e., stored at client device 104), and source indicator 418-c displays an “S” indicating that the audio track corresponding to audio track affordance 416-c is available via a streaming audio service provider. In FIG. 4A, back navigation affordance 410, when activated (e.g., by a touch input from the user), causes client device 104 to display a previous user interface (e.g., a home screen for the application). In FIG. 4A, scroll bar 412 indicates that the balance of the audio tracks can be viewed by scrolling downwards. FIG. 4A also illustrates detecting contact 420 (e.g., a tap gesture) on touch screen 406 at a location corresponding to audio track affordance 416-c.

FIG. 4B illustrates client device 104 displaying a next user interface of the process for generating the media item on touch screen 406. In FIG. 4B, the user interface prompts the user of client device 104 to choose a portion of the audio track (e.g., the audio track corresponding to audio track affordance 416-c) in response to detecting contact 420 selecting audio track affordance 416-c in FIG. 4A. In FIG. 4B, the user interface includes album cover art 426, audio track information 428, and a waveform 430 for the audio track corresponding to audio track affordance 416-c. For example, audio track information 428 includes artist name(s), track title, the number of media items created with the audio track, and hashtags associated with the audio track corresponding to audio track affordance 416-c.

In FIG. 4B, waveform 430 optionally includes an end indicator 434 for selected portion 436 of the audio track corresponding to audio track affordance 416-c. For example, end indicator 434 defaults to the 30 second point in the audio track based on a predetermined or default audio portion size of 30 seconds. In FIG. 4B, the user interface also includes back navigation affordance 422, which, when activated (e.g., by a touch input from the user), causes client device 104 to display the previous user interface (e.g., the user interface in FIG. 4A), forward navigation affordance 424, which, when activated (e.g., by a touch input from the user), causes client device 104 to display a next user interface (e.g., the user interface in FIG. 4D) of the process for generating the media item, and continue affordance 432, which, when activated (e.g., by a touch input from the user), causes client device 104 to display the next user interface (e.g., the user interface in FIG. 4D) of the process for generating the media item. FIG. 4B further illustrates detecting a left-to-right dragging gesture with contact 438 on touch screen 406 originating at a location corresponding to end indicator 434.

FIG. 4C illustrates moving end indicator 434 left-to-right and displaying start indicator 440 in response to the detecting the dragging gesture in FIG. 4B. For example, selected portion 436 remains a 30 second interval of the audio track between end indicator 434 and start indicator 440. FIG. 4C also illustrates detecting contact 442 (e.g., a tap gesture) on touch screen 406 at a location corresponding to continue affordance 432.

FIG. 4D illustrates client device 104 displaying a live feed from a back-facing camera of client device 104 in response to detecting contact 442 selecting continue affordance 432 in FIG. 4C.

FIGS. 6A-6F illustrate a flowchart diagram of a client-side method 600 of generating a media item in accordance with some embodiments. In some embodiments, method 500 is performed by an electronic device with one or more processors and memory. For example, in some embodiments, method 600 is performed by a mobile device (e.g., client device 104, FIGS. 1-2) or a component thereof (e.g., client-side module 102, FIGS. 1-2). In some embodiments, method 600 is governed by instructions that are stored in a non-transitory computer readable storage medium and the instructions are executed by one or more processors of the electronic device. Optional operations are indicated by dashed lines (e.g., boxes with dashed-line borders).

The client device displays (602) a first user interface including a plurality of audio tracks. FIG. 4A, for example, shows client device 104 displaying a first user interface of a process for generating a media item on touch screen 406. In FIG. 4A, for example, the first user interface includes a plurality of audio track affordances 416 corresponding to audio tracks.

The client device detects (604) a first user input selecting one of the plurality of audio tracks. FIG. 4A, for example, shows client device 104 detecting contact 420 selecting audio track affordance 416-c corresponding to an audio track.

In some embodiments, in response to detecting the first user input and prior to displaying the second user interface for recording a video clip, the client device displays (606) an audio track portion selection user interface that enables the user of the client device to select a portion of the selected audio track, and the client device detects a user input selecting a specified portion of the audio track. In response to detecting contact 420 selecting audio track affordance 416-c, FIGS. 4B-4C, for example, show client device 104 displaying a user interface prompting the user of client device 104 to choose a portion of the audio track corresponding to audio track affordance 416-c. FIG. 4B, for example, shows client device 104 detecting a dragging gesture with contact 438 to move end indicator 434 and along with it portion 436 of the audio track corresponding to audio track affordance 416-c. FIG. 4C, for example, shows client device 104 detecting contact 442 selecting portion 436 of the audio track corresponding to audio track affordance 416-c. In some embodiments, portion 436 is a predetermined maximum length (e.g., a 15, 30, etc. second chunk) in relation to a predetermined maximum size for the media item (e.g., in terms of seconds or bytes). In some embodiments, portion 436 is only limited by the length of the audio track. In FIGS. 4B-4C, for example, portion 436 is a predetermined 30 second chunk of the audio track corresponding to audio track affordance 416-c both before and after moving end indicator 434.

In response to detecting the first user input, the client device displays (608) a second user interface for recording a video clip. After selecting the audio track in FIG. 4A, FIG. 4D, for example, shows client device 104 displaying a second user interface on touch screen 406 of a process for generating a media item. In FIG. 4D, for example, the user interface prompts the user of client device 104 to record a video clip for the media item by tapping anywhere on touch screen 406.

In some embodiments, the process for generating the media item proceeds with client device 104 displaying the first user interface for selecting one of a plurality of audio tracks (e.g., FIGS. 4A-4C) for the media item prior to the second user interface for recording a video clip (e.g., FIG. 4D) for the media item. Alternatively, in some embodiments, the process for generating a media item proceeds with client device 104 displaying the second user interface for recording a video clip (e.g., FIG. 4D) for the media item prior to the first user interface for selecting one of a plurality of audio tracks (e.g., FIGS. 4A-4C) for the media item.

In some embodiments, displaying the second user interface includes (610) displaying a video feed from a first camera of the client device. In some embodiments, a feed from at least one of the one or more cameras of client device 104 is automatically displayed in the second user interface after selecting the audio track. FIG. 4D, for example, shows client device 104 displaying a live feed from a back-facing camera of client device 104 on touch screen 406. FIG. 4L, for example, shows client device 104 displaying a live feed from the front-facing camera of client device 104 on touch screen 406.

The client device detects (612) a second user input to initiate recording of the video clip (e.g., a tap gesture anywhere on the second user interface). FIG. 4D, for example, shows client device 104 detecting contact 454 at a location on touch screen 406 to initiate recording of a first video clip for the media item from the live feed from the back-facing camera of client device 104.

In some embodiments, in response to detecting the second user input, the client device displays (614) progress of recording of the video clip in the second user interface (e.g., a progress bar is filled while recording the video clip). FIG. 4E, for example, shows client device 104 displaying progress indicator 456 for the first video clip being recorded. In some embodiments, a predetermined maximum length for the media item limits the length of the one or more video clips being shot (e.g., 15, 30, 60, etc. seconds). For example, the horizontal width of the screen represents the predetermined maximum length for the one or more video clips associated with the media item. For example, in FIG. 4E, the length of progress indicator 456 indicates the length of the first video clip in relation to the predetermined maximum size for the media item.

In some embodiments, prior to detecting the third user input (616), the second user interface includes (618) a plurality of audio and/or video effect affordances associated with a plurality of audio and/or video effects, and, after detecting the second user input and prior to detecting the third user input, the client device: detects a fifth user input selecting one of the plurality of audio and/or video effect affordances; and in response to detecting the fifth user input, applies the audio and/or video effect corresponding to the selected one of the plurality of audio and/or video effect affordances to the video clip being recorded. FIG. 4L, for example, shows client device 104 displaying the user interface for recording a video clip including effects region 450 with a plurality of audio and/or video effect affordances 452 corresponding to audio and/or video effects. In FIG. 4L, for example, the thick frame surrounding effect affordance 452-a indicates that the effect corresponding to effect affordance 452-a (i.e., no effect) is being applied to the video feed displayed on touch screen 406. FIG. 4M, for example, shows client device 104 detecting contact 494 selecting effect affordance 452-c corresponding to a dots video effect. FIG. 4N, for example, shows client device 104 applying, in real-time, the dots video effect to the third video clip being recorded in response to detecting contact 494 selecting effect affordance 452-c in FIG. 4M. In some embodiments, the user of client device 104 is also able to apply, in real-time, overlay text, such as a title, to the video clip being recorded.

In some embodiments, prior to detecting the third user input (616), the client device (620): detects a sixth user input (e.g., moving a slider associated with the effect or performing a specified gesture) after applying the audio and/or video effect corresponding to the selected one of the plurality of audio and/or video effect affordances to the video clip being recorded; and in response to detecting the sixth user input, varies one or more parameters associated with the audio and/or video effect being applied to the video clip being recorded. In FIG. 4N, for example, the user interface includes effect modifier 496 for modifying the dots video effect in real-time. For example, effect modifier 496, in FIG. 4N, is a slider that increases the density of dots when slid left-to-right and decreases the density of dots when slid right-to-left. In some embodiments, audio and/or video effects in which multiple actual parameters have been projected to one-dimensional controls that map to simultaneously change to many actual controls, in order to simplify the user experience. In some embodiments, the control of effects is via “invisible” sliders actuated by simply touching and dragging across the screen. In some embodiments, the audio and/or video effects have interactive components that can be controlled and manipulated at run-time via user inputs from a subsequent viewer.

In some embodiments, the effects are downloaded from server system 108 at run-time including computer-readable instructions or scripts for the effects written in a language such as GLSL, accompanied by effect metadata indicating effect type, effect version, effect parameters, a table mapping interactive modalities (e.g., touch, gesture, sound, vision, etc.) to effect parameters, and so on. In this way, the choice, number, and type of effect can be varied at run-time. In some embodiments, a web-based content management server (CMS) is available for the real-time browser-based authoring and uploading of effects to the server, including real-time preview of effects on video and/or audio (e.g., using technologies such as WebGL). In some embodiments, the audio and/or video effects have interactive components that can specified and customized by authors via the CMS, and then be controlled and manipulated at run-time via user inputs.

The client device detects (622) a third user input to stop recording of the video clip (e.g., a tap gesture anywhere on the second user interface). FIG. 4E, for example, shows client device 104 detecting contact 458 at a location on touch screen 406 to stop recording of the first video clip for the media item.

In some embodiments, in response to detecting the third user input, the client device displays (624) a representation of the video clip in the second user interface. In FIG. 4F, for example, the user interface includes representation 462 of the first video clip recorded in FIGS. 4D-4E.

In some embodiments, the second user interface includes a first affordance, and, prior to detecting the fourth user input (626), the client device (628): detects a fifth user input selecting the first affordance; and, in response to detecting the fifth user input, displays a video feed from a second camera of the client device, where the second camera is different from the first camera. FIG. 4K, for example, shows client device 104 displaying a live feed from the back-facing camera of client device 104 on touch screen 406 and detecting contact 488 on touch screen 406 at a location corresponding to affordance 446 (e.g., the first affordance). FIG. 4L, for example, shows client device 104 displaying a live feed from the front-facing camera of client device 104 on touch screen 406 in response to detecting contact 488 selecting affordance 446 in FIG. 4K.

In some embodiments, the second user interface includes a second affordance, and, prior to detecting the fourth user input (626), the client device (630): detects a fifth user input selecting the second affordance; in response to detecting the fifth user input, displays one or more pre-existing video clips and/or one and more pre-existing images; and detects a sixth user input selecting one or more video clips and/or one or more images from the one or more pre-existing video clips and/or the one and more pre-existing images. FIG. 4F, for example, shows client device 104 detecting contact 464 on touch screen 406 at a location corresponding to affordance 448 (e.g., the second affordance). FIG. 4G, for example, shows client device 104 displaying first pre-existing media content selection panel 466 in response to detecting contact 464 selecting affordance 448 in FIG. 4F. For example, in FIG. 4G, first pre-existing media content selection panel 466 includes a plurality of video regions 471, where each of video regions 471 is associated with a pre-recorded video 472 from a video library associated with the user of client device 104 (e.g., video library 252, FIG. 2) and includes the recording date/time, length, comments, and location for the associated pre-recorded video 472. For example, in FIG. 4G, first pre-existing media content selection panel 466 also includes image library affordance 470, which, when activated (e.g., by a touch input from the user) causes client device 104 to display a second content selection panel including one or more pre-captured images in an image library associated with the user of client device 104 (e.g., image library 254, FIG. 2). FIG. 4G, for example, also shows client device 104 detecting contact 474 on touch screen 406 at a location corresponding to video region 471-a associated with pre-recorded video 472-a.

In some embodiments, in response to detecting the sixth user input, the client device displays (632) the one or more video clips and/or one or more images as a live source in the second user interface, where the live source is treated identically to a video feed from a first camera of the client device. FIG. 4H, for example, shows client device 104 displaying pre-recorded video 472-a as a live feed on touch screen 406 in response to detecting contact 474 selecting video region 471-a in FIG. 4G.

In some embodiments, displaying the one or more images as the live source includes animating (634) the one or more images with effects. For example, when one or more pre-captured images are selected from the image library, the one or more selected images are displayed on touch screen 406 as a live source (e.g., a slideshow) with animation effects (e.g., two- and three-dimensional movements, scale, pixel effects, distortion effects, transition effects, and so on) between images.

In some embodiments, the video clip is a first video clip, and, prior to detecting the fourth user input (626), the client device (636): detects a seventh user input to initiate recording of a second video clip from the one or more video clips and/or one or more images being displayed in the second user interface; and detects an eighth user input to stop recording of the second video clip. In some embodiments, the user of client device 104 is able to “sample” from pre-recorded video clips as if the pre-recorded video clip is a love source. FIG. 4H, for example, shows client device 104 detecting contact 478 at a location on touch screen 406 to initiate recording of a second video clip for the media item from pre-recorded video 472-a. FIG. 4I, for example, shows client device 104 detecting contact 482 at a location on touch screen 406 to stop recording of the second video clip for the media item.

In some embodiments, the video clip is a first video clip, and, prior to detecting the fourth user input (626), the client device (638): detects a fifth user input to initiate recording of a second video clip; and detects a fifth user input to stop recording of the second video clip. FIG. 4L, for example, shows client device 104 detecting contact 490 at a location on touch screen 406 to initiate recording of a third video clip for the media item from the live feed from the front-facing camera of client device 104. FIG. 4N, for example, shows client device 104 detecting contact 498 at a location on touch screen 406 to stop recording of the third video clip for the media item.

In some embodiments, prior to detecting the fourth user input (626), the client device displays (640) a sequence of representations of two or more distinct video clips at least including the first video clip and the second video clip. In some embodiments, representations of the recorded video clips are arranged according to the sequence in which the video clips were recorded in the process for generating the media item. In FIG. 4J, for example, the user interface includes a sequence of representations for two video clips: (1) representation 462 of the first video clip recorded in FIGS. 4D-4E; and (2) representation 484 of the second video clip recorded in FIGS. 4H-4I. In FIG. 4O, for example, the user interface includes a sequence of representations for three video clips: (1) representation 462 of the first video clip recorded in FIGS. 4D-4E; (2) representation 484 of the second video clip recorded in FIGS. 4H-4I; and (3) representation 4100 of the third video clip recorded in FIGS. 4L-4N.

In some embodiments, prior to detecting the fourth user input (626), the client device (642): detects a gesture dragging a respective representation in the sequence of representations from a first position in the sequence of representations to a second position in the sequence of representations; and, in response to detecting the gesture, displays the respective representation in the second position in the sequence of representations. In some embodiments, the user of client device 104 is able to reorder the recorded video clips by dragging a representation of a respective video clip them a first location to a second location in the sequence of representations. FIGS. 4O-4P, for example, show client device 104 detecting a dragging gesture with contact 4102 on touch screen 406 originating at a location corresponding to representation 4100 and moving representation 4100 of the third video clip out of the third position in the sequence of representations. FIG. 4Q, for example, shows client device 104 displaying representation 4100 of the third video clip in a second position in the sequence of representations and representation 484 of the second video clip in the third position in the sequences of representations in response to detecting the dragging gesture in FIGS. 4O-4P.

In some embodiments, prior to detecting the fourth user input (626), the client device (644): detects a gesture dragging a respective representation in the sequence of representations from a first position in the sequence of representations to a second position in the sequence of representations; and, in response to detecting the gesture, ceases to display the respective representation in the sequence of representations. In some embodiments, the user of client device 104 is able to delete a video clip by dragging a representation corresponding to the video clip off the screen or towards the top or edge of the screen, and detecting the end of a dragging gesture (e.g., liftoff of the contact comprising the dragging gesture). FIGS. 4Q-4R, for example, shows client device 104 detecting a dragging gesture with contact 4104 on touch screen 406 originating at a location corresponding to representation 484 and moving representation 484 of the second video clip from a third position in the sequence of representations to the right edge of touch screen 406. FIG. 4S, for example, shows client device 104 ceasing to display representation 484 in response to detecting the dragging gesture in FIGS. 4Q-4R.

In some embodiments, prior to detecting the fourth user input (626), the client device (646): detects a gesture at a position in a respective representation in the sequence of representations; and, in response to detecting the gesture: splits the respective representation into two distinct video clips based on the position; and records a third video clip starting from the position. In some embodiments, the user of client device 104 is able to split a video clip into two separate video clips based on the location of a user input selecting a representation of the video clip and, also, record a new video clip between the two separate video clips. FIG. 4S, for example, shows client device 104 detecting contact 4106 (e.g., a long press gesture) on touch screen 406 at a location corresponding to representation 462. FIG. 4T, for example, shows client device 104 splitting the first video clip corresponding to representation 462 into two separate video clips corresponding to representations 4108 and 4110 and, also, recording a fourth video clip associated with progress indicator 4112 between the two separate video clips in response to detecting contact 4106 in FIG. 4S. In one embodiment, the user of client device 104 is able to select an insertion along the video timeline somewhere between the beginning and end of a video clip corresponding to the location of an input gesture at a location corresponding to the representation for the video clip. Subsequently, in response to detecting a user input to initiate recording of a video clip, the video clip corresponding to the representation is split into two separate video clips at the insertion point, and a new video clip begins recording at the insertion point, moving all subsequent video clips forward in time in proportion to the duration of the new video clip.

In some embodiments, prior to detecting the fourth user input (626), the client device (648): detects a gesture at a location corresponding to a respective representation in the sequence of representations; in accordance with a determination that the gesture is in a first direction, increases the frame rate of the video clip associated with the respective representation; and in accordance with a determination that the gesture is in a second direction substantially opposite to the first direction, decreases the frame rate of the video clip associated with the respective representation. In some embodiments, the video clip was recorded at a maximum available frame rate (e.g., 120 frames per second (fps)). For example, with respect to FIG. 4L, the user of client device 104 is able to perform a pinch gesture at a location corresponding to representation 462 to increase the frame rate (and decrease the duration) of the video clip associated with representation 462. In this example, the frame rate is increased up to the displayable maximum frame-rate (e.g. 60 fps) after which point client device 104 is configured to skip or blend frames (e.g. playing the 2nd, 4th, 6th, and so on frames, or playing blended frames 2+3, 4+5, 6+7, and so on) to provide the continued illusion of faster-and-faster motion. In another example, with respect to FIG. 4L, the user of client device 104 is able to perform a de-pinch gesture (substantially opposite to the punch gesture) at a location corresponding to representation 462 to decrease the frame rate (and increase the duration) of the video clip associated with representation 462. In this example the frame rate is decreased down to the displayable minimum frame-rate (e.g. 15 fps) and thereafter client device 104 is configured to generate interpolated frames (e.g. interpolating between frames 3 and 4 to generate frame 3.5) to create ultra-slow-motion effects.

In some embodiments, the user of client device 104 is able to select the frame rate to record video in slow motion. In some embodiments, the user of client device 104 is able to import video clips from video library 252 (FIG. 2) and subsequently select the frame rate to sample the previously recorded video in slow motion. In some embodiments, after recording a video or sampling previously recorded video, the user of client device 104 is able to select a reverse-motion feature whereby the video is played back in reverse and the user of client device 104 is able to sample the video in reverse-motion for the media item to be generated. In some embodiments, before recording a video or sampling previously recorded video, the user of client device 104 is able to select a time-lapse feature whereby the run time of the video will be compressed to a selected time-lapse length (e.g., 5 minutes of captured video is sped up to fit a selected 2 minute time-lapse length). In some embodiments, before recording a video or sampling previously recorded video, the user of client device 104 is able to select a time-stretch feature whereby the run time of the video will be r stretched to a selected time-lapse length (e.g., 2 minutes of captured video is slowed down to fit a selected 5 minute time-stretch length).

In some embodiments, after detecting the third user input and prior to detecting the fourth user input, the client device detects (650) a fifth user input selecting one or more video effects and/or one or more audio effects in order to create an interactive media item, where a subsequent viewer of the interactive media item is able to interact with the video and/or audio associated with the interactive media item using the selected one or more video effects and/or one or more audio effects. In some embodiments, interactive audio and/or video effects selected by the author are embedded into the media item to make the media item interactive for subsequent viewers. For example, user inputs from a subsequent viewer control and manipulate these interactive effects at run-time. In some embodiments, effect ranges and parameters for the interactive effects are also selected by the author. FIG. 4X, for example, shows client device 104 displaying a first interactive effects selection panel 4140 in response to detecting contact 4138 selecting “Make Interactive” affordance 4136 in FIG. 4W. In FIG. 4X, for example, first interactive effects selection panel 4140 includes a plurality of video effect affordances 4146 each corresponding to an interactive video effect type 4147 and including a preview of the corresponding interactive video effect. In FIG. 4X, for example, first interactive effects selection panel 4140 also includes audio effects affordance 470, which, when activated (e.g., by a touch input from the user) causes client device 104 to display a second interactive effects selection panel including a plurality of interactive audio effects. FIG. 4X, for example, shows also shows client device 104 detecting contact 4148 on touch screen 406 selecting video effect affordance 4146-a corresponding to a respective video effect. In FIG. 4Y, for example, the thick frame surrounding video effect affordance 4146-a indicates that the video effect corresponding to video effect affordance 4146-a has been selected in response to detecting contact 4148 in FIG. 4X. For example, in FIG. 4Y, the user of client device 104 is able to select zero or more interactive audio and/or video effects in addition to the interactive video effect corresponding to video effect affordance 4146-a.

The client device detects (652) a fourth user input to publish the media item based on the video clip and the selected audio track. For example, in response to detecting a user input selecting forward navigation affordance 4132, in FIG. 4W or 4Z, client device 104 causes the media item to be published and displays a home screen for the application.

In response to detecting the fourth user input, the client device publishes (654) the media item to a server, including sending to the server information identifying the selected audio track, the video clip, and information related to synchronization of the selected audio track and the video clip. For example, in response to detecting a user input selecting forward navigation affordance 4132 (e.g., in FIG. 4W or FIG. 4Z) or a user input selecting any of sharing options 4134 (e.g., in FIG. 4W), client device 104 causes the media item generated in FIGS. 4A-4U to be published by sending, to server system 108, information associated with the media item. In some embodiments, the information at least includes: (A) first information identifying at least a portion of an audio track selected in FIGS. 4A-4C; and (B) second information identifying the recorded video clips corresponding to representations 4108, 4116, 4110, and 4100 in FIG. 4U. In some embodiments, in response to publishing the media item, server system 108 downloads the one or more video clips identified in the second information and creates a metadata structure (e.g., metadata structure 500, FIG. 5) at least including a pointer to each of the one or more video clips and a pointer to the audio track.

In some embodiments, in response to detecting the fourth user input, the client device displays (656) a third user interface including one or more options for sharing the media item (e.g., affordances for email, SMS, social media outlets, etc.). FIG. 4Z, for example, shows client device 104 detecting contact 4152 on touch screen 406 at a location corresponding to social media application A 4134-a. For example, in response to detecting contact 4152 selecting social media application A 4134-a, client device 104 causes a link to the generated media item to be placed on a profile page in social media application A corresponding to the user of client device 104. In another example, in response to detecting contact 4152 selecting social media application A 4134-a, client device 104 causes a link to the generated media item to be placed on a profile page in social media application A corresponding to the user of client device 104 and the generated media item is published by sending, to server system 108, information associated with the media item.

FIGS. 7A-7B illustrate a flowchart diagram of a server-side method 700 of generating the media item in accordance with some embodiments. In some embodiments, method 700 is performed by an electronic device with one or more processors and memory. For example, in some embodiments, method 700 is performed by a server (e.g., server system 108, FIGS. 1 and 3) or a component thereof (e.g., server-side module 106, FIGS. 1 and 3). In some embodiments, method 700 is governed by instructions that are stored in a non-transitory computer readable storage medium and the instructions are executed by one or more processors of the electronic device. Optional operations are indicated by dashed lines (e.g., boxes with dashed-line borders).

The server receives (702) first information, from a client device, identifying at least a portion of an audio track associated with the media item. For example, in response to detecting a user input selecting forward navigation affordance 4132, in FIG. 4W or FIG. 4Z, client device 104 causes the media item to be published by sending, to server system 108, first information identifying at least a portion of an audio track selected in FIGS. 4A-4C associated with the media item generated in FIGS. 4A-4U.

In some embodiments, the first information also identifies (704) a specified portion of the audio track (e.g., the specified portion of the audio track includes at least a predetermined amount of the audio track such as 5, 10, 15, 30, etc. seconds). For example, the first information identifying at least a portion of the audio track selected in FIGS. 4A-4C, identifies portion 436 (e.g., a 30 second chunk of the audio track corresponding to audio track affordance 416-c) selected in FIG. 4C.

In some embodiments, the first information further identifies (706) an audio start time indicator corresponding to the specified portion of the audio track. For example, the first information includes a start timestamp associated with start indicator 440 and an end timestamp associated with end indicator 434 for portion 436 of the audio track corresponding to audio track affordance 416-c selected in FIG. 4C.

The server receives (708) second information, from the client device, identifying one or more media files associated with the media item. In some embodiments, the one or more media files include one or more video clips recorded by the user during the process for creating the media item, one or more pre-recorded video clips selected from the user's video library 252 (FIG. 2), one or more pre-captured images selected from the user's image library 256 (FIG. 2), or video clips and/or images selected from a remote media file source 126, as shown in FIG. 1 (e.g., YouTube or Flickr). For example, in response to detecting a user input selecting forward navigation affordance 4132, in FIG. 4W or FIG. 4Z, client device 104 causes the media item to be published by also sending, to server system 108, second information identifying the recorded video clips corresponding to representations 4108, 4116, 4110, and 4100 in FIG. 4U associated with the media item generated in FIGS. 4A-4U.

In some embodiments, in response to receiving the second information, the server obtains (710) the one or more media files identified by the second information. For example, server system 108 downloads the video clips corresponding to representations 4108, 4116, 4110, and 4100 in FIG. 4U to media files database 114, as shown in FIGS. 1 and 3. In another example, server system 108 causes the video clips corresponding to representations 4108, 4116, 4110, and 4100 in FIG. 4U to be saved to a database located remotely from server system 108.

The server generates (712) a metadata structure corresponding to the media item generated by the client device, where (714): the metadata structure enables synchronization of at least the portion of the audio track with the one or more media files; and the metadata structure includes: a pointer to the audio track identified by the first information; and a pointer to the one or more media files identified by the second information. For example, in response to receiving the first information and the second information, server system 108 generates metadata structure 500, as shown in FIG. 5, corresponding to the media item generated in FIGS. 4A-4U. In FIG. 5, for example, metadata structure 500 includes: (A) one or more video file pointer fields 508 including a pointer or link (e.g., a URL) for each of the one or more video clips associated with the media item; and (B) an audio pointer for each of the one or more audio tracks associated with the media item. For example, metadata structure 500 also includes an audio start time field to synchronize the audio track with the one or more media files associated with the media item. In another example, metadata structure 500 does not include an audio start time field and the audio track is predefined to start from its beginning.

In some embodiments, the first information includes information identifying a first source of the audio track, and the client device (716): determines a second source of the audio track, where the metadata structure further includes a source table for the audio track, including a first audio start time indicator associated with the first source and a second audio start time indicator associated with the second source. For example, an audio source table for an audio track associated with a media item is required to maintain synchronized play back of the audio track when the audio track is available from two or more streaming audio service providers (e.g., Spotify, SoundCloud, Rdio, Pandora, etc.) and the various streaming versions of the audio track include differences such as varying start times. In FIG. 5, for example, metadata structure 500 includes one or more audio source tables 510 for each of the one or more audio tracks associated with the media item. In this example, a representative audio source table for a respective audio track includes one or more pairings for each of one or more audio sources for the respective audio track. In this example, a first representative pairing includes audio pointer 512-a to a first source of the respective track (e.g., SoundCloud) and start time 514-a for the start time of the respective track from the first source, and a second representative pairing includes audio pointer 512-b to a second source of the respective track (e.g., Pandora) and start time 514-b for the start time of the respective track from the second source.

In some embodiments, the server receives (718) third information, from the client device, identifying one or more audio effects and/or one or more video effects to be applied to the audio track and/or the one or more media files, where the third information further includes an effects table with one or more entries, each of the one or more entries includes the type of audio or video effect applied to the audio track or the one or more media files and a timestamp indicating the start time of the audio or video effect. In some embodiments, audio and/or video effects are created during the process of generating a media item as a metadata description of effects, that are to be applied at run-time in the application or browser of the subsequent viewer, to preserve the quality of effects, and to allow infinite remixing, revision, and future high-quality compatibility with new devices and resolution. For example, the third information includes effects table 516, in FIG. 5. In this example, each entry 518 in effects table 516 corresponds to an audio and/or video effect selected by the author of the media item. Continuing with this example, the entry 518-a includes one or more of: the identifier, name, or handle associated with the user who added the effect; the effect type; the effect version; the content (e.g., media file and/or audio track) subjected to the effect; a start time (t1) for the effect; an end time (t2) for the effect; and one or more preset parameters (p1, p2, . . . ) for the effect. In some embodiments, the entry also includes computer-readable instructions for generating the effect such as GLSL scripts.

In some embodiments, the server (720): analyzes the at least one of the identified audio track and the one or more media files to obtain a digital fingerprint for at least one of the identified audio track and the one or more media files; determines whether the digital fingerprint matches an audio track or video clip in a database; and in accordance with a determination that digital fingerprint matches an audio track or video clip in a database, performs an action specified by an owner of the audio track or video clip. In some embodiments, owners of copyrighted audio tracks or video clips upload at least a sample of the audio tracks or video clips to reference database 332 (FIG. 3) associated with the provider of the application. In some embodiments, the owner of the copyrighted audio tracks or video clips also identifies a preference for treating user generated media items that include audio tracks or video clips that matches their copyrighted audio tracks or video clips. In some embodiments, server system 108 or a component thereof (e.g., analyzing module 322, FIG. 3) analyzes the audio tracks and video clips associated with the user generated media item to determine a digital fingerprint for the audio tracks and video clips. In some embodiments, when server system 108 or a component thereof (e.g., determining module 324, FIG. 3) determines that the digital fingerprint for the audio tracks and video clips associated with the user generated media item matches copyrighted audio tracks and/or video clips in reference database 332, server system 108 or a component thereof (e.g., performing module 326, FIG. 3) is configured to perform an action corresponding to the preference identified by the owner of the copyrighted audio tracks and/or video clips. For example, copyright holder may allow users to freely use their copyrighted audio tracks and/or video clips, prefer to collect a portion of ad revenue generated from views of the user generated media item, or prefer to scrub their copyrighted audio tracks and/or video clips from the user generated media item (e.g., muting the copyrighted audio).

In some embodiments, the server (722): receives a command to share the media item; and in response to the command to share the media item: flattens the media item into a single stream with combined audio and video; and generates a link for accessing the single stream. For example, in response to detecting contact 4152 selecting social media application A 4134-a in FIG. 4Z, server system 108 receives, from client device 104, a command to share the media item generated in FIGS. 4A-4U. In response to receiving the command, server system 108 causes a link to the media item to be placed on a profile page in social media application A corresponding to the user of client device 104. In some embodiments, server system 108 or a component thereof (e.g., modifying module 328, FIG. 3) generates a flattened version of the media item by combining the one or more audio tracks, one or more video clips, and zero or more effects associated with the media item into a single stream or digital media item. In some embodiments, the link placed on the profile page in social media application A corresponds to the flattened version of the media item for web browsers.

In some embodiments, sharing a media item is accomplished by a specialized web player that recreates a subset of the functions of the application and runs in a web browser, such as some combination of: synchronizing audio and video streams from different sources during playback; applying real-time effects; allowing interaction with the player; allowing sharing and re-sharing of the media item on social networks or embedded in web pages, etc.
